请问c为什么不对

问题如下：

The level of significance of a hypothesis test is best used to:

选项：

A.

calculate the test statistic.

B.

define the test’s rejection points.

C.

specify the probability of a Type II error.

解释：

B is correct. The level of significance is used to establish the rejection points

of the hypothesis test. A is incorrect because the significance level is not used to

calculate the test statistic; rather, it is used to determine the critical value. C is

incorrect because the significance level specifies the probability of making a Type

I error.
